Objective: To test effectiveness of the LEAP (Learn Engage Act Process) Program on engaging frontline Veteran Health Administration (VHA) medical center teams in continuous quality improvement (QI), a core capability for learning health systems., Data Sources and Study Setting: Data sources included VHA electronic health record (EHR) data, surveys, and LEAP coaching field notes., Study Design: A staggered difference-in-differences study was conducted. Fifty-five facilities participated in LEAP across eight randomly assigned clusters of 6-8 facilities per cluster over 2 years. Non-participating facilities were used as controls. A MOVE! weight management program team completed a Plan-Do-Study-Act cycle of change supported by learning curriculum, coaching, and virtual collaboratives in LEAP facilities. Primary outcome was program reach to Veterans. A mixed-effects model compared pre- versus post-LEAP periods for LEAP versus control facilities. LEAP adherence, satisfaction, and cost to deliver LEAP were evaluated., Data Collection/extraction Methods: Thirty months of facility-level EHR MOVE! enrollment data were included in analyses. LEAP Satisfaction and QI skills were elicited via surveys at baseline and 6-month post-LEAP., Principal Findings: Fifty-five facilities were randomly assigned to eight time-period-based clusters to receive LEAP (71% completed LEAP) and 82 non-participating facilities were randomly assigned as controls. Reach in LEAP and control facilities was comparable in the 12-month pre-LEAP period (p = 0.07). Though LEAP facilities experienced slower decline in reach in the 12-month post-LEAP period compared with controls (p < 0.001), this is likely due to unexplained fluctuations in controls. For LEAP facilities, satisfaction was high (all mean ratings >4 on a 5-point scale), self-reported use of QI methods increased significantly (p-values <0.05) 6 months post-LEAP, and delivery cost was $4024 per facility-based team., Conclusion: Control facilities experienced declining reach in the 12-month post-LEAP period, but LEAP facilities did not, plus they reported higher engagement in QI, an essential capability for learning health systems., (Published 2024.

Introduction: Despite all efforts of national and local approaches, obesity rates continue to rise worldwide. It is increasingly recognized that the complexity of obesity should be further addressed by incorporating a systems perspective when implementing approaches. Such an approach has four interconnected system levels: events, structures, goals, and beliefs, in which small changes ('leverage points') can lead to substantial changes in the functioning of the entire system. The current research examined the functioning of five Dutch municipalities' healthy weight approaches (HWAs) and the leverage point themes that can be identified in their system., Methods: Thirty-four semi-structured interviews were conducted with various stakeholders about the HWA, including policy advisors, care professionals, practice professionals, and citizens. An inductive thematic analysis was performed., Results: Three main themes were identified: 1) HWA organization structure, 2) collaboration between professionals, and 3) citizen participation. Across all system levels, we identified leverage point themes. The upper-levels events and structures occurred the most and were explained by underlying goals and beliefs. Leverage point themes regarding "HWA organization structure" were municipal processes, such as perceived impact; diversity of themes, activities, and tasks; network; and communication strategies, such as messages about the HWA. Leverage point themes regarding "collaboration between professionals" were linking pins, indicating central players within the network; motivation and commitment including support base; and stimulating one another to work on the HWA by spurring other professionals into action. Lastly, leverage point themes under "citizen participation" included reaching the target group, e.g., look for entry points; and citizens' motivation, including customization., Discussion: This paper provides unique insights into HWAs' leverage point themes that can lead to substantial changes in how the entire system functions and makes suggestions about underlying leverage points to help stakeholders improve their HWA. Future research could focus on studying leverage points within leverage point themes., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Bogt et al.

Purpose : In light of the increasing prevalence of overweight and obesity, understanding the experiences, strategies and challenges encountered when trying to achieve substantial, sustainable weight loss is an important area to investigate. We systematically evaluated qualitative studies focusing on the accounts of individuals who have achieved sustained weight loss to create a comprehensive picture of the experience of sustainable weight loss. Methods : Included studies were peer-reviewed studies that qualitatively assessed the views and experiences of adults who previously had or currently have overweight or obesity who successfully lost weight and who subsequently maintained or regained weight. The evidence was systematically synthesized, which enabled the formulation of clear themes and recommendations. Results : The 15 chosen studies included the accounts of 294 individuals. We found that continuous monitoring and goal setting, driven by sustained motivation and encouraging experiences, while resisting ever present challenges and enduring discouraging experience encapsulates the experience of sustained, substantial weight loss. Conclusions : This review aims to provide a comprehensive understanding of the experiences, strategies and challenges encountered when trying to achieve substantial, sustained weight loss. Additional research taking into account findings from this review and others of its kind will enhance the formulation of treatment protocols.

As a major public health concern, childhood obesity is a multifaceted and multilevel metabolic disorder influenced by genetic and behavioral aspects. While genetic risk factors contribute to and interact with the onset and development of excess body weight, available evidence indicates that several modifiable obesogenic behaviors play a crucial role in the etiology of childhood obesity. Although a variety of systematic reviews and meta-analyses have reported the effectiveness of several interventions in community-based, school-based, and home-based programs regarding childhood obesity, the prevalence of children with excess body weight remains high. Additionally, researchers and pediatric clinicians are often encountering several challenges and the characteristics of an optimal weight management strategy remain controversial. Strategies involving a combination of physical activity, nutritional, and educational interventions are likely to yield better outcomes compared to single-component strategies but various prohibitory limitations have been reported in practice. This review seeks to (i) provide a brief overview of the current preventative and therapeutic approaches towards childhood obesity, (ii) discuss the complexity and limitations of research in the childhood obesity area, and (iii) suggest an Etiology-Based Personalized Intervention Strategy Targeting Childhood Obesity (EPISTCO). This purposeful approach includes prioritized nutritional, educational, behavioral, and physical activity intervention strategies directly based on the etiology of obesity and interpretation of individual characteristics.

Background: Engagement with conventional weight management group programmes is low., Objective: To understand participant experience of accessing an adapted programme via videoconference., Participants: Adults with obesity (BMI ≥ 35kg/m 2 ), referred to an NHS Dietetics service in Wales, were offered a group videoconference weight management programme as an optional alternative to in-person groups. Thirteen participants (mean age 48.5 ± 20.2 years, 8 female) recruited to two videoconference groups were interviewed., Study Design: A Registered Dietitian delivered a behavioural programme using Skype for Business in 10 sessions over 6 months. Participants joined the groups from any Internet-connected device with a webcam. Participant perspectives were audiorecorded in one-to-one, semi-structured interviews. Interviews were transcribed verbatim and thematically analysed using self-determination theory as a theoretical framework., Results: Ten themes were identified, three relating to service engagement and seven relating to behaviour change facilitation. Key themes in engagement included 'reduced burden', described as saving time and travel and 'reduced threat' as participants perceived joining a group from home as less daunting compared to attending in-person. Despite reporting some initial technical difficulties with establishing video and audio connection, participants described beneficial peer support although not physically with other group members., Conclusion: Accessing a group weight management programme via videoconference may be the preferred option for some participants, overcoming some of the barriers to access to standard in-person programmes, particularly in rural areas. Participants are able to experience peer support via videoconference. During the COVID-19 pandemic, weight management programmes could utilize videoconference groups to continue to provide support., (© 2020 The Authors.

Introduction: Class 3 obesity (BMI ≥ 40 kg/m 2 ) is a growing health problem worldwide associated with considerable comorbidity including Type 2 diabetes mellitus (T2DM). The multidisciplinary medical management of obesity can be difficult in T2DM due to potential weight gain from medications including sulphonylureas and insulin. However, newer weight-neutral/losing diabetes medications can aid additional weight loss. The aim of this study was to compare weight loss outcomes of patients with and without T2DM, and in patients with T2DM, to compare diabetes outcomes and change in medications at 6 months., Methods: All patients entering a multidisciplinary weight management metabolic program in a publicly funded hospital clinic in Sydney between March 2018 and March 2019, with BMI ≥ 40 kg/m 2 and aged ≥18 years were included. Data was collected from patient clinical and electronic notes at baseline and 6 months., Results: Of the 180 patients who entered the program, 53.3% had T2DM at baseline. There was no difference in percentage weight loss in those with or without T2DM (4.2 ± 4.9% vs. 3.6 ± 4.7%, p = 0.35). Additionally, T2DM patients benefited from a 0.47% reduction in HbA1c ( p < 0.01) and a reduction in the number of medications from baseline to 6 months (1.8 ± 1.0/patient vs. 1.0 ± 1.2/patient, p < 0.001). T2DM patients who started on weigh-neutral/losing medications in the program lost more weight than those started on weight-gaining medications (7.7 ± 5.3% vs. 2.4 ± 3.8%, p = 0.015)., Conclusions: Patients with class 3 obesity had significant weight loss at 6 months in this program. Patients with T2DM at baseline had comparable weight loss at 6 months, a significant improvement in glycaemic control, and a reduction in diabetes medication load. Additionally, patients with T2DM who were started on weight-neutral/losing medications lost significantly more weight than those started on weight-gaining medications, and these medications should be preferentially used in class 3 obesity and comorbid T2DM., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this paper.

Background: Physical activity is associated with a reduced risk of numerous types of cancer and plays an important role in maintaining a healthy weight. Wearable physical activity trackers may supplement behavioral intervention and enable researchers to study how determinants like self-efficacy predict physical activity patterns over time., Methods: We used multistate models to evaluate how self-efficacy predicted physical activity states among overweight and obese individuals participating in a 26-week weight loss program ( N = 96). We specified five states to capture physical activity patterns: (i) active (i.e., meeting recommendations for 2 weeks), (ii) insufficiently active, (iii) nonvalid wear, (iv) favorable transition (i.e., improvement in physical activity over 2 weeks), and (v) unfavorable transition. We calculated HRs of transition probabilities by self-efficacy, body mass index, age, and time., Results: The average prevalence of individuals in the active, insufficiently active, and nonvalid wear states was 13%, 44%, and 16%, respectively. Low self-efficacy negatively predicted entering an active state [HR, 0.51; 95% confidence interval (CI), 0.29-0.88]. Obesity negatively predicted making a favorable transition out of an insufficiently active state (HR, 0.61; 95% CI, 0.40-0.91). Older participants were less likely to transition to the nonvalid wear state (HR, 0.53; 95% CI, 0.30-0.93). Device nonwear increased in the second half of the intervention (HR, 1.73; 95% CI, 1.07-2.81)., Conclusions: Self-efficacy is an important predictor for clinically relevant physical activity change in overweight and obese individuals. Multistate modeling is useful for analyzing longitudinal physical activity data., Impact: Multistate modeling can be used for statistical inference of covariates and allow for explicit modeling of nonvalid wear.

Objective: To assess weight and HbA 1c changes in the Healthier You: National Health Service Diabetes Prevention Programme (NHS DPP), the largest DPP globally to achieve universal population coverage., Research Design and Methods: A service evaluation assessed intervention effectiveness for adults with nondiabetic hyperglycemia (HbA 1c 42-47 mmol/mol [6.0-6.4%] or fasting plasma glucose 5.5-6.9 mmol/L) between program launch in June 2016 and December 2018, using prospectively collected, national service-level data in England., Results: By December 2018, 324,699 people had been referred, 152,294 had attended the initial assessment, and 96,442 had attended at least 1 of 13 group-based intervention sessions. Allowing sufficient time to elapse, 53% attended an initial assessment, 36% attended at least one group-based session, and 19% completed the intervention (attended >60% of sessions). Of the 32,665 who attended at least one intervention session and had sufficient time to finish, 17,252 (53%) completed: intention-to-treat analyses demonstrated a mean weight loss of 2.3 kg (95% CI 2.2, 2.3) and an HbA 1c reduction of 1.26 mmol/mol (1.20, 1.31) (0.12% [0.11, 0.12]); completer analysis demonstrated a mean weight loss of 3.3 kg (3.2, 3.4) and an HbA 1c reduction of 2.04 mmol/mol (1.96, 2.12) (0.19% [0.18, 0.19]). Younger age, female sex, Asian and black ethnicity, lower socioeconomic status, and normal baseline BMI were associated with less weight loss. Older age, female sex, black ethnicity, lower socioeconomic status, and baseline overweight and obesity were associated with a smaller HbA 1c reduction., Conclusions: Reductions in weight and HbA 1c compare favorably with those reported in recent meta-analyses of pragmatic studies and suggest likely future reductions in participant type 2 diabetes incidence., (© 2019 by the American Diabetes Association.)

Introduction: Previous trials finding an effect of self-monitoring on weight loss have considered the effect to be mediated by self-regulatory processes. However, a qualitative think-aloud study asking people to record thoughts and feelings during weighing showed that self-regulation occurs only rarely without further instruction. The aim of this trial is to test a novel intervention guiding people through the self-regulatory processes to see whether it facilitates weight loss., Methods and Analyses: A parallel group, randomised controlled trial will be conducted to test the concept that a self-regulation intervention for weight loss increases weight loss compared with daily self-weighing without further support. One hundred participants with a body mass index ≥30 kg/m 2 will be randomised to either the control or intervention group. The control group will be asked to weigh themselves daily for 8 weeks, the intervention group will be encouraged to follow the self-regulation intervention. They will be prompted to weigh daily, track their weight using an app, plan daily actions for weight loss and reflect on their action plans on a weekly basis. This self-regulation cycle will allow them to experiment with different weight loss strategies and identify effective and sustainable actions. Primary and process outcomes will be measured at baseline and 8 weeks' follow-up. Linear regression analysis of the primary outcome, weight change, will assess the early effectiveness of the intervention. The process outcomes liking, perceived effectiveness, as well as usage and barriers with regard to the self-regulation intervention, will be assessed through qualitative analysis of follow-up interviews and quantitative analysis of adherence rates and responses to a final questionnaire., Ethics and Dissemination: This trial was reviewed and approved by the NHS National Research Ethics Committee and the Health Research Authority (reference number: 18/SC/0482). The findings of the trial will be published in peer reviewed journals and presented at conferences., Trial Registration Number: ISRCTN14148239, prerecruitment., Protocol Version: Version 1.1, 7 December 2018., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Introduction: We examined the effects of a digitally delivered, type 2 diabetes mellitus prevention program (DPP) for a low-income population., Methods: We conducted a nonrandomized clinical trial with matched controls. The intervention group was offered a digital DPP, a web-based and mobile-based program including 52 weeks of participation in an educational curriculum, health coaching, and peer support., Results: A total of 227 participants enrolled. At baseline, 34.6 was the mean body mass index, and 5.8 was the mean HbA 1c . For the intervention group, mean weight loss was 4.4% at the 12-month follow-up., Conclusion: The modified DPP successfully engaged participants and resulted in weight loss. Low-income patients with prediabetes benefitted from a digitally delivered diabetes intervention. This prevention method should be accessible to a low-income population.

Background and Objectives: Programmed shared medical appointments (pSMAs) are an extension of shared medical appointments (SMAs) for managing chronic diseases. Acceptance and outcomes of a trial for weight management are reported here., Method: Six programmed sessions in weight management were carried out in seven NSW primary healthcare centres., Results: Seventy-seven per cent of 216 participants (64 male, 102 female) completed at least four of six pSMAs over 16-18 weeks ('adherers'). Eighty-five per cent of adherers approved of pSMAs, and 73% said they would prefer these over a standard clinical consult. Providers also rated the process highly. Overall mean weight loss over 12 months was 3.2% (95% confidence interval [CI]: 2.2, 4.3; P <0.001). For adherers, mean weight loss was 4.3% for males (95% CI: 2.6, 6.1; P <0.001) and 4.2% for females (95% CI: 2.7, 5.7; P <0.001), with 46% of males and 35% of females maintaining clinically significant losses (>5%) after 12 months. pSMAs were calculated to be four times more cost effective and up to seven times more time effective than 1:1 consultations for weight loss., Discussion: pSMAs are a popular, cost and time-effective adjunct to standard clinical management.

Background: Childhood obesity prevalence continues to be at high levels in the United Kingdom (UK). South Asian children (mainly Pakistani and Bangladeshi origin) with excess adiposity are at particular risk from the cardiovascular consequences of obesity. Many community-based children's weight management programmes have been delivered in the UK, but none have been adapted for diverse cultural communities. The aim of the Child weigHt mANaGement for Ethnically diverse communities (CHANGE) study, was to culturally adapt an existing children's weight management programme for children aged 4-11 years so that the programme was more able to meet the needs of families from South Asian communities., Methods: The adaptation process was applied to First Steps, an evidence informed programme being delivered in Birmingham (a large, ethnically diverse city). A qualitative study was undertaken to obtain the views of South Asian parents of children with excess weight, who had fully or partially attended, or who had initially agreed but then declined to attend the First Steps programme. The resulting data were integrated with current research evidence and local programme information as part of a cultural adaptation process that was guided by two theoretical frameworks., Results: Interviews or focus groups with 31 parents in their preferred languages were undertaken. Themes arising from the data included the need for convenient timing of a programme in a close familiar location, support for those who do not speak English, the need to focus on health rather than weight, nutritional content that focuses on traditional and Western diets, more physical activity content, and support with parenting skills. The data were mapped to the Behaviour Change Wheel framework and Typology of Cultural Adaptation to develop an intervention programme outline. The research evidence and local programme information was then used in the detailed planning of the programme sessions., Conclusions: The process of cultural adaptation of an existing children's weight management programme resulted in a theoretically underpinned programme that is culturally adapted at both the surface and deep structural levels., Trial Registration: ISRCTN81798055 , registered: 13/05/2014.

Background: Due to multiple and interacting factors, Latino children are disproportionately at risk for overweight and obesity in the United States. Childhood obesity increases the risk for adverse physical and psychosocial outcomes throughout the lifespan. Intensive behavioral interventions recommended in primary care settings may not conform to current practices, and the most vulnerable populations are often unable to access these services. Community Health Workers (CHWs) offer a promising approach to bridging the gap between vulnerable communities and culturally competent services. La Vida Buena (The Good Life) is an 8-week family-focused intervention for Latino children 5-8 years old and their parents or caregivers who are patients at a Federally-Qualified Community Health Center (FQHC). It is a culturally and linguistically appropriate curriculum, facilitated by CHWs, that targets family behaviors to foster a healthy lifestyle in order to prevent and mitigate childhood overweight and obesity., Methods: The primary objective is to test the effectiveness of the La Vida Buena (LVB) childhood obesity program among Latino children 5-8 years old and their families as compared with a single educational session. This study uses a parallel two-arm quasi-experimental design. The intervention group receives the 8-week La Vida Buena intervention and the comparison group receives a single educational session. The primary outcome is the change in the child's BMI z-score from baseline to 6 months., Discussion: The implementation and evaluation of La Vida Buena may inform research and practice for linking Latino patients in FQHCs to culturally responsive community-based childhood obesity interventions. It will also contribute to the literature about CHWs as facilitators of behavior change for families underserved by health services and preventive programs. La Vida Buena can serve as a culturally and linguistically appropriate early intervention curriculum that will foster a healthy home environment for childhood obesity mitigation and prevention., Trial Registration: The trial was retrospectively registered on December 18, 2018. The ClinicalTrials.gov Identifier is NCT03781856.

Background: Beginning in 2017 we have conducted a 3-arm randomised controlled trial (RCT) to determine the effectiveness of an early obesity intervention in the first two years of life using either telephone or Short Message Service (SMS) support for mothers. The trial recruited 1155 mothers from their third trimester of pregnancy. This protocol is for a new trial to build on the existing trial using the mother-child dyads retained at 24 months for recruitment to the new RCT. The aim of this new trial is to test whether use of a combination of telephone and SMS interventions is effective in promoting healthy eating and physical activity, as well as reducing child body mass index (BMI) at 3 years of age., Methods: We will conduct a parallel RCT with an estimated sample of 750 mother-child dyads retained from the existing trial at 24 months. Mothers who completed the 24 months survey, including a telephone survey and measurement of child's height and weight will be invited to participate in the new trial. Informed consent will be obtained at the 24 months survey. The participating mother-child dyads will then be randomly allocated to the intervention (combined telephone and text messaging intervention) or the control group. The intervention will comprise three staged telephone consultations and text messages after each of the three intervention booklets is mailed to mothers at specific time-points between two and three years of child age. The main trial outcome measures include a) BMI and BMI z-score measured at 36 months, b) diet, physical activity and screen time c) cost-effectiveness, and d) feasibility and acceptability of the intervention., Discussion: This unique opportunity to link two studies will expedite project start up time, utilise existing research infrastructure and systems to run the study, and optimise the use of an already engaged population of study participants. It can address a significant knowledge gap regarding early obesity prevention for children aged 2 to 3 years. The feasibility and effectiveness of the combined telephone and SMS intervention will indicate whether this is a scaleable, broad-reach and low-cost early obesity intervention., Trial Registration: The trial was registered with the Australian Clinical Trial Registry ( ACTRN12618001571268 ) on 20/09/2018.

Background: To describe the identification, adaptation, and testing of an evidence-based pediatric weight management program for a health disparate community., Methods: A community advisory board (CAB) of decision-makers and staff from local health care, public health, and recreation organizations engaged with academic partners to select an evidence-based program (EBP) for local implementation. Three EBPs were identified (Traffic Light, Bright Bodies, Golan and colleagues Home Environmental Model) and each EBP was rated on program characteristics, implementation and adaptation, and adoptability. Following selection of the EBP that was rated highest, the POPS-CAB made adaptations based on the program principles described in peer-reviewed publications. The adapted intervention, iChoose, was then pilot tested in 3 iterative phases delivered initially by research partners, then co-delivered by research and community partners, then delivered by community partners. The RE-AIM framework was used to plan and evaluate the iChoose intervention across all waves with assessments at baseline, post program (3 months), and follow-up (6 months)., Results: Bright Bodies rated highest on program characteristics and adoptability (p's < 0.05), while Home Environmental Model rated highest on implementation factors (p < 0.05). Qualitatively, the selection focused on important program characteristics and on matching those characteristics to the potential to fit within the community partner services. The adapted program-iChoose-had 18% reach and with participants that were representative of the target population on age, gender, ethnicity, and race. Effectiveness was demonstrated by modest, but significant reductions in BMI z-scores at post-program compared to baseline (M Δ  = - 0.047; t = - 2.11, p = 0.046). This decrease returned to values similar to baseline 3 months (M Δ  = 0.009) after the program was completed. Implementation fidelity was high and implementation fidelity did not differ between community or research delivery agents., Conclusion: The process to help organizations identify and select evidence-based programs appropriate for their community led to consensus on a single EBP. While iChoose was successful in initiating changes in BMI z-scores, could be implemented in a low resource community with fidelity, it was insufficient to lead to sustained child BMI z-scores. In response to these data, maintenance of program effects and delivery are the current focus of the CBPR team.

Background: There are many factors across different sectors that contribute to inequities in obesity levels. This implies the need for action across different government departments and policy domains (hereafter referred to as whole of government multisectoral action). In this study we explored the public policy attention given to inequities in obesity using an Australian case study., Methods: Interviews were conducted with 33 stakeholders involved in the development and implementation of the whole of government Healthy Weight Initiative (HWI). A thematic analysis was undertaken to identify ways in which government policy makers and implementers explicitly or implicitly described how actions delivered through the HWI addressed inequities in obesity within the population., Results: The analysis revealed that the focus of the HWI was predominantly aimed at the general population, with minimal attention given to addressing the social distribution of obesity. The reasons for this were explained in terms of five themes: (1) rationale for a population wide approach; (2) when to apply an equity lens, (3) issues of government responsibility, (4) philosophically opposing concepts of equity, and (5) tensions across departments as a result of competing concepts of equity., Conclusions: It is important to create a shared understanding plus a concern for addressing inequities in public policy, regardless of whether or not a universal population-wide or a targeted approach is being applied. It is also important that policies and programs address the social distribution of obesity while understanding local contexts and needs. In striving to develop policy that brings an explicit focus on health equity, policymakers must consider the sociological, political, economic, and philosophical tensions at play between different policy actors and government departments, and identify how to navigate these without reverting to siloed working.

Background: Describing how and why an evidence-based intervention is adapted for a new population and setting using a formal evaluation and an adaptation framework can inform others seeking to modify evidence-based weight management interventions for different populations or settings. The Working for You intervention was adapted, to fit a workplace environment, from Be Fit Be Well, an evidence-based intervention that targets weight-control and hypertension in patients at an outpatient clinic. Workplace-based efforts that promote diet and activity behavior change among low-income employees have potential to address the obesity epidemic. This paper aims to explicitly describe how Be Fit Be Well was adapted for this new setting and population., Methods: To describe and understand the worksite culture, environment, and policies that support or constrain healthy eating and activity in the target population, we used qualitative and quantitative methods including key informant interviews, focus groups, and a worker survey; these data informed intervention adaptation. We organized the adaptations made to Be Fit Be Well using an adaptation framework from implementation science., Results: The adapted intervention, Working for You, maintains the theoretical premise and evidence-base underpinning Be Fit Be Well. However, it was modified in terms of the means of delivery (i.e., rather than using interactive voice response, Working for You employs automated SMS text messaging), defined as a modification to context by the adaptation framework. The adaptation framework also includes modifications to content; in this case the behavioral goals were modified for the target population based on updated science related to weight loss and to target a workplace population (e.g., a goal to avoiding free food at work)., Conclusions: If effective, this scalable and relatively inexpensive intervention can be translated to other work settings to reduce obesity and diabetes risk among low-SES workers, a group with a higher prevalence of these conditions. Using a formal evaluation and framework to guide and organize how and why an evidence-based intervention is adapted for a new population and setting can push the field of intervention research forward., Trial Registration: ClinicalTrials.gov: NCT02934113 ; Received: October 12, 2016; Updated: November 7, 2017.

The evidence base for weight loss programs in men is limited. Gaining a greater understanding of which personal characteristics and pretreatment behaviors predict weight loss and attrition in male-only studies would be useful to inform the development of future interventions for men. In December 2010, 159 overweight/obese men (mean age = 47.5 years; body mass index = 32.7 kg/m 2 ) from the Hunter Region of New South Wales, Australia, participated in a randomized controlled trial testing the effectiveness of two versions of a 3-month gender-targeted weight loss program. In the current analyses, social-cognitive, behavioral, and demographic pretreatment characteristics were examined to determine if they predicted weight loss and attrition in the participants over 6 months. Generalized linear mixed models (intention-to-treat) revealed weight change was associated with education level ( p = .02), marital status ( p = .03), fat mass ( p = .045), sitting time on nonwork ( p = .046), and workdays ( p = .03). Workday sitting time and marital status accounted for 6.5% ( p = .01) of the variance in the final model. Attrition was associated with level of education ( p = .01) and body fat percentage ( p = .01), accounting for 9.5% ( p = .002) of the variance in the final model. This study suggests men who spend a lot of time sitting at work, especially those who are not married, may require additional support to experience success in self-administered weight loss programs targeting males. Additional high-quality evidence is needed to improve the understanding which pretreatment behaviors and characteristics predict weight loss and attrition in men.

Background: The prevalence of childhood obesity poses an urgent global challenge. The World Health Organization (WHO) Commission on Ending Childhood Obesity recommends the provision of appropriate family-based, lifestyle weight management services through universal health care to support families of children with overweight or obesity; however, there are few examples of their implementation 'at scale'. The purpose of this research was to compare and contrast the impact of system and organisational factors on the implementation of childhood obesity management services within two Australian States (New South Wales and Queensland) to comprehensively describe their influence on the achievement of the WHO recommendation., Methods: Purposeful stratified sampling was used to select health service study sites (n = 16) representative of program implementation (none, discontinued, repeated) and geographic location within each State. Within each health service site, staff involved in program delivery, co-ordination and management roles participated (n = 39). An additional 11 staff involved in implementation at State level also participated. The Consolidated Framework for Implementation Research (CFIR) was used to develop interview scripts. Telephone interviews were recorded and transcribed. Transcripts were thematically coded and scored according to CFIR constructs and rating rules to identify enablers and barriers to implementation according to sample characteristics., Results: New South Wales achieved ongoing implementation; Queensland did not. Enablers included a quality evidence-based program, State government recognition of the urgency of the health issue and a commitment to address it, formally appointed and funded internal implementation leaders, strong communication and reporting at all levels. Barriers included the complexity of the health issue, in particular a lack of clear roles and responsibilities for local health service delivery, inadequate ongoing funding and challenges in meeting the diverse needs of families., Conclusions: This research is an important progression of the evidence base in relation to the translation of childhood obesity management trials into routine health service delivery. Understanding enablers and barriers to program implementation 'at scale' is imperative to inform future planning and investment by Australia and WHO member states to meet their commitment to deliver childhood weight management services as part of universal health coverage.

Background: There is increasing recognition of the value of "real-world evidence" in evaluating health care services. Registry-based, observational studies conducted in clinical settings represent a relevant model to achieve this directive. Starting in 2010, we undertook a longitudinal, observational study (the CANadian Pediatric Weight management Registry [CANPWR]), which is embedded in 10 multidisciplinary, pediatric weight management clinics across Canada. The objective of this paper was to share the lessons our team learned from this multi-centre project., Methods: Data sources included a retrospective review of minutes from 120 teleconferences with research staff and investigators, notes taken during clinical site visits made by project leaders, information from quality control processes to ensure data accuracy and completeness, and a study-specific survey that was sent to all sites to solicit feedback from research team members (n = 9). Through an iterative process, the writing group identified key themes that surfaced during review of these information sources and final lessons learned were developed., Results: Several key lessons emerged from our research, including the (1) value of pilot studies and central research coordination, (2) need for effective and regular communication, (3) importance of consensus on determining outcome measures, (4) challenge of embedding research within clinical practice, and (5) difficulty in recruiting and retaining participants. The sites were, in spite of these challenges, enthusiastic about the benefits of participating in multi-centre collaborative studies., Conclusion: Despite some challenges, multi-centre observational studies embedded in pediatric weight management clinics are feasible and can contribute important, practical insights into the effectiveness of health services for managing pediatric obesity in real-world settings.

Background: PEACH™QLD translated the PEACH™ Program, designed to manage overweight/obesity in primary school-aged children, from efficacious RCT and small scale community trial to a larger state-wide program. This paper describes the lessons learnt when upscaling to universal health coverage., Methods: The 6-month, family-focussed program was delivered in Queensland, Australia from 2013 to 2016. Its implementation was planned by researchers who developed the program and conducted the RCT, and experienced project managers and practitioners across the health continuum. The intervention targeted parents as the agents of change and was delivered via parent-only group sessions. Concurrently, children attended fun, non-competitive activity sessions. Sessions were delivered by facilitators who received standardised training and were employed by a range of service providers. Participants were referred by health professionals or self-referred in response to extensive promotion and marketing. A pilot phase and a quality improvement framework were planned to respond to emerging challenges., Results: Implementation challenges included engagement of the health system; participant recruitment; and engagement. A total of 1513 children (1216 families) enrolled, with 1122 children (919 families) in the face-to-face program (105 groups in 50 unique venues) and 391 children (297 families) in PEACH™ Online. Self-referral generated 68% of enrolments. Unexpected, concurrent and, far-reaching public health system changes contributed to poor program uptake by the sector (only 56 [53%] groups delivered by publicly-funded health organisations) requiring substantial modification of the original implementation plan. Process evaluation during the pilot phase and an ongoing quality improvement framework informed program adaptations that included changing from fortnightly to weekly sessions aligned with school terms, revision of parent materials, modification of eligibility criteria to include healthy weight children and provision of services privately. Comparisons between pilot versus state-wide waves showed comparable prevalence of families not attending any sessions (25% vs 28%) but improved number of sessions attended (median = 5 vs 7) and completion rates (43% vs 56%)., Conclusions: Translating programs developed in the research context to enable implementation at scale is complex and presents substantial challenges. Planning must ensure there is flexibility to accommodate and proactively manage the system changes that are inevitable over time., Trial Registration: ACTRN12617000315314 . This trial was registered retrospectively on 28 February, 2017.

Purpose: This article presents a reflective account of Patient and Public Involvement (PPI) in the development of obesity and binge eating research., Method: We established Patient Advisory Groups (PAGs) at two English regional National Health Service (NHS) weight management services. PPI was evaluated as follows: (i) PAG members completed a Post Participation Evaluation Questionnaire, (ii) PAG meetings captured group discussion on PPI involvement, (iii) practitioner and researchers produced written reflections on PPI and (iv) sources one to three were consolidated during reflections that took place via e-mail and telephone correspondence between researchers and practitioners, culminating in a summary SKYPE meeting between one practitioner and one researcher involved in the PAGs., Results: Results in the form of reflections suggest guidelines on undertaking PPI were helpful with regard 'what to do', but less helpful on 'how'. For example, suggestions for the management of interpersonal factors such as eliciting self-disclosure and managing power differentials are insufficiently addressed in existing guidelines., Conclusions: The present case study illustrated how interpersonal considerations can help or hinder the optimal use of PPI. Recommendations for practitioners and researchers planning PPI are offered.

Objectives: Paediatric obesity predicts adult obesity, and alarming new data in New Zealand reveals that obesity among the young continues to rise. In this study, we used a novel solution-focused paradigm, or appreciative inquiry perspective, to explore the factors that influence not just obese but non-obese states (that is, healthy weight as well as obesity), in Pacific adolescents (aged 13-17) living in socioeconomically deprived neighbourhoods., Methods: Sixty-eight parents and adolescents from 30 families were recruited and interviewed, resulting in 15 obese and 15 healthy weight adolescents participating in the study., Results: Our findings showed that, despite living in low socioeconomic circumstances, parents were able to alter their micro-environments to prevent obesity in their children. Parents with healthy weight adolescents had food rules in the home and monitored their children's eating and television viewing time., Conclusions: An appreciative inquiry approach to obesity research can uncover resiliency factors within families that can be applied to obesity prevention and treatment programs. Implications for public health: Appreciative inquiry methodology is a promising alternative qualitative research strategy for developing health interventions for low-income ethnic minority communities., (© 2017 The Authors.)

Objectives: Obesity in children and adolescents is a worldwide dramatic health problem, for which treatment is mostly unsuccessful. Therefore, prevention is the most important measure to tackle this problem. The 'EDDY' study as an interventional cohort study with a 1-year lifestyle intervention aimed to affect the lifestyle and nutrition habits of adolescents by intervention with nutritional training and sports programs to prevent obesity., Methods: Four Viennese schools were cluster-randomized into an intervention group and a control group. A total of 141 pupils aged 11-14 years were included. The intervention group received a comprehensive, age-appropriate training on nutrition and lifestyle exercise intervention for 12 months. Before and after intervention and at two follow-ups, subjects were anthropometrically measured. In addition, knowledge of nutritional issues and eating habits were measured with questionnaires., Results: The data imply an improvement of nutrition knowledge, a significant reduction in the consumption of junk food (p = 0.01), sweets (p = 0.001) and salty snacks (p < 0.001) as well as a slight improvement of physical performance after intervention. Although there was a trend for a less increase of body fat in the intervention group, no significant changes could have been shown in the anthropometric data., Conclusions: An age-adjusted lifestyle intervention based on dietary training and exercise can improve the nutritional knowledge and eating habits of school children., (© 2018 The Author(s) Published by S.

The impact of childhood obesity on the Swedish Health Care system is described. Childhood Obesity and Diabetes Type 2 is increasing for the last 10 years, but not Diabetes Type 1. Thus, prevention is needed. How to define prevention of obesity? Could treatment of childhood obesity be regarded as prevention of adult obesity? Of course it could, but we are lacking a long term follow-up from childhood to adulthood. However, we know that childhood obesity is a risk factor for adult disease. But we need long-lasting results in children to being able to state that we have prevented adult obesity. What about treatment of children with overweight, i.e. defined as the less severe level of an increased body weight as opposed to obesity? There are few if any studies restricting the treatment only to overweight children. Normally, obese children are treated, and some overweight children are added usually to increase the study sample. Then of course promotion of a healthy lifestyle could be of major interest. Finally, the traditional concept of primary prevention seems to be the only solution that is realistic according to many. However, there is no clear pattern when primary prevention works., (© 2018 The Author(s) Published by S. Karger GmbH, Freiburg.)

Background: Translation encompasses the continuum from clinical efficacy to widespread adoption within the healthcare service and ultimately routine clinical practice. The Parenting, Eating and Activity for Child Health (PEACH™) program has previously demonstrated clinical effectiveness in the management of child obesity, and has been recently implemented as a large-scale community intervention in Queensland, Australia. This paper aims to describe the translation of the evaluation framework from a randomised controlled trial (RCT) to large-scale community intervention (PEACH™ QLD). Tensions between RCT paradigm and implementation research will be discussed along with lived evaluation challenges, responses to overcome these, and key learnings for future evaluation conducted at scale., Methods: The translation of evaluation from PEACH™ RCT to the large-scale community intervention PEACH™ QLD is described. While the CONSORT Statement was used to report findings from two previous RCTs, the REAIM framework was more suitable for the evaluation of upscaled delivery of the PEACH™ program. Evaluation of PEACH™ QLD was undertaken during the project delivery period from 2013 to 2016., Results: Experiential learnings from conducting the evaluation of PEACH™ QLD to the described evaluation framework are presented for the purposes of informing the future evaluation of upscaled programs. Evaluation changes in response to real-time changes in the delivery of the PEACH™ QLD Project were necessary at stages during the project term. Key evaluation challenges encountered included the collection of complete evaluation data from a diverse and geographically dispersed workforce and the systematic collection of process evaluation data in real time to support program changes during the project., Conclusions: Evaluation of large-scale community interventions in the real world is challenging and divergent from RCTs which are rigourously evaluated within a more tightly-controlled clinical research setting. Constructs explored in an RCT are inadequate in describing the enablers and barriers of upscaled community program implementation. Methods for data collection, analysis and reporting also require consideration. We present a number of experiential reflections and suggestions for the successful evaluation of future upscaled community programs which are scarcely reported in the literature., Trials Registration: PEACH™ QLD was retrospectively registered with the Australian New Zealand Clinical Trials Registry on 28 February 2017 (ACTRN12617000315314).

Background: The health outcomes of men continue to be poorer than women globally. Challenges in addressing this problem include difficulties engaging men in weight loss programs as they tend to view these programs as contrary to the masculine narrative of independence and self-reliance. Researchers have been turning towards sports fans to engage men in health promotion programs as sports fans are typically male, and tend to have poor health habits., Methods: Developed from the highly successful gender-sensitized Football Fans in Training program, Hockey Fans in Training (Hockey FIT) recruited 80 male hockey fans of the London Knights and Sarnia Sting who were overweight or obese into a weekly, 90-minute classroom education and group exercise program held over 12 weeks; a 40-week minimally-supported phase followed. A process evaluation of the Hockey FIT program was completed alongside a pragmatic randomized controlled trial and outcome evaluation in order to fully explore the acceptability of the Hockey FIT program from the perspectives of coaches delivering and participants engaged in the program. Data sources included attendance records, participant focus groups, coach interviews, assessment of fidelity (program observations and post-session coach reflections), and 12-month participant interviews., Results: Coaches enjoyed delivering the program and found it simple to deliver. Men valued being among others of similar body shape and similar weight loss goals, and found the knowledge they gained through the program helped them to make and maintain health behaviour changes. Suggested improvements include having more hockey-related information and activities, greater flexibility with timing of program delivery, and greater promotion of technology support tools., Conclusions: We confirmed Hockey FIT was an acceptable "gender-sensitized" health promotion program for male hockey fans who were overweight or obese. Minor changes were required for optimization, which will be evaluated in a future definitive trial., Trial Registration: NCT02396524 (Clinicaltrials.gov). Date of registration: Feb 26, 2015.

Background: For more than a decade, the Veterans Health Administration (VHA) has offered MOVE!, a comprehensive lifestyle intervention for weight management. However, there is limited knowledge to inform resource allocation decisions at the health system level-for example, the choice between reaching new veterans with weight management treatment, re-engaging veterans who have stopped attending, and/or increasing contact with current MOVE!, Objective: To inform VHA policy and planning, this VHA-wide study examines the relationship between MOVE! participation and weight outcomes., Design: A longitudinal observational study of veterans across VHA who participated in MOVE!., Participants: Veterans who initiated their most recent episode of MOVE! care between 2004 and 2014., Main Measures: Weight measurements were abstracted from VHA electronic health records. The primary outcome was the proportion of veterans with clinically relevant weight loss. The predictor of interest was number of MOVE! contacts during the 12 months following MOVE! initiation., Key Results: The cohort consisted of 237,577 veterans (87.4% male; mean age 54.4 years), who had 5.3 contacts on average in the 12 months following initiation. Veterans with 2-5 contacts had the same odds of achieving clinically relevant weight loss as veterans with only one contact (adjusted OR: 1.00, 95% CI: 0.98-1.03). Veterans with 6-9, 10-13, 14-17, and 18 or more contacts had significantly higher odds of clinically relevant weight loss (adjusted OR: 1.17, 95% CI: 1.13-1.20; adjusted OR: 1.53, 95% CI: 1.47-1.59; adjusted OR: 1.84, 95% CI: 1.74-1.94; adjusted OR: 2.21, 95% CI: 2.12-2.31, respectively)., Conclusions: Veterans with ≥6 MOVE! contacts in the year following treatment initiation were significantly more likely to achieve clinically relevant weight loss than those with one contact, with greater participation further increasing the odds of clinically relevant weight loss. While further characterization of weight loss predictors is needed, the VHA should provide policy guidance that supports increasing participation among veterans who have initiated MOVE!.

Background: The obesity epidemic has been growing steadily across the whole world, and so far not a single country has been able to reverse it. The cause of obesity is stated by the World Health Organization as an energy imbalance between calories consumed and calories expended. However, growing evidence suggests that the calorie imbalance concept may not be sufficient to manage and reverse the obesity epidemic., Objective: To discuss the use of the calorie imbalance concept and its elements as a tool for weight management as well as its possible negative consequences and implications for public health, with the aim to point toward the need of an updated concept for causes of obesity. This update should guide public health interventions more efficiently to limit obesity by preventing weight gain or promoting weight loss., Methods: This is a literature reviews based on a semi-structured approach to determine the material to be examined., Results: After revisiting general facts about fat generation and accumulation, we propose an updated concept for the causes of obesity including diet composition and hormonal regulation of fat metabolism., Conclusions: We discuss how this updated concept could benefit the overall efficiency of strategies against obesity, and hypothesize how potential resistance to adopting this new view could be lowered.

Background: Despite National guidance recommending their use, there is uncertainty regarding the best way to deliver weight management services across the UK and worldwide., Methods: To ascertain access, provision and interventions used in lifestyle Tier 2 and specialist Tier 3 weight management services in Scotland, a survey was distributed to all mainland health boards covering pathways for referral, eligibility criteria, intervention format and definitions of attendance completion and adherence., Results: Nine Health boards provided information on their weight management services. The provision of services was low. Only four health boards offered services for those with a BMI 25-30 kg/m 2 . Lifestyle Tier 2 services were mainly weekly or fortnightly group sessions for 8-12 weeks delivered by dietitians or community workers. Specialist Tier 3 services were largely similar to lifestyle Tier 2 services. The provision of specialist interventions including pharmacotherapy, cognitive behavioural therapy sessions and low-calorie prescribed diets was low., Conclusions: This national survey has illustrated large disparities in the provision of weight management across Scotland, a likely consequence of uncertainty regarding best practice. There is a clear requirement for the evaluation of existing services to identify those that lead to the largest improvements in health outcomes and are cost-effective., (© The Author 2015.

Purpose: The aim of the study was to test a tailored lifestyle intervention for helping obese primary care patients achieve weight loss and increase physical activity., Methods: We conducted a 24-month randomized clinical trial in Rhode Island. Primary care physicians identified obese, sedentary patients motivated to lose weight and increase their moderate to vigorous physical activity. These patients were randomized to 1 of 2 experimental groups: enhanced intervention (EI) or standard intervention (SI). Both groups received 3 face-to-face weight loss meetings. The enhanced intervention group also received telephone counseling calls, individually tailored print materials, and DVDs focused on diet and physical activity. Active intervention occurred in year 1 with a tapered maintenance phase in year 2., Results: Two hundred eleven obese, sedentary patients were recruited from 24 primary care practices. Participants were 79% women and 16% minorities. They averaged 48.6 years of age, with a mean body mass index (BMI) of 37.8 kg/m(2), and 21.2 minutes/week of moderate to vigorous physical activity. Significantly more EI participants lost 5% of their baseline weight than SI participants (group by visit, P <.001). The difference was significant during active treatment at 6 months (37.2% EI vs 12.9% SI) and 12 months (47.8% vs 11.6%), but was no longer significant during the maintenance phase at 18 months (31.4% vs 26.7%,) or 24 months (33.3% vs 24.6%). The EI group reported significantly more minutes of moderate to vigorous physical activity over time than the SI group (group by visit, P = 0.04). The differences in minutes per week at 6 months was 95.7 for the EI group vs 68.3 minutes for the SI group; at 12 months, it was 126.1 vs 73.7; at 18 months, 103.7 vs 63.7, and at 24 months, 101.3 vs 75.4. Similar trends were found for absolute weight loss and the percentage reaching national guidelines for physical activity., Conclusion: A home-based tailored lifestyle intervention in obese, sedentary primary care patients was effective in promoting weight loss and increasing moderate to vigorous physical activity, with the effects peaking at 12 months but waning at 24 months., (© 2016 Annals of Family Medicine, Inc.)

Background: National Institute for Health and Care Excellence (NICE) guidance on adult weight management recommends interventions are multi-component. We aimed to assess the implementation and health benefits of a primary care referral to an adult multi-component weight management intervention in a community setting. The intervention was offered through Primary care in National Health Service (NHS) South Gloucestershire, UK, from Oct 2008 to Nov 2010, in partnership with statutory, community and commercial providers. The scheme offered 12 weeks' community based concurrent support of dietary (Weight Watchers, WW), physical activity (Exercise on Prescription, EOP) and behavioural change (motivational interviewing) components to obese adults. Funding was available for 600 places., Results: Five hundred and fifty nine participants engaged with the intervention, mean age 48 years, 88% female. Mean weight loss for all engagers was 3.7 kg (95 % confidence interval 3.4, 4.1). Participants completing the intervention achieved the largest weight reduction (mean loss 5.9 kg; 5.3, 6.6). Achievement of 5% weight loss was higher in completers (58%; 50, 65) compared to non-completers (19%; 12, 26) and people who only participated in one commercial component of the intervention (either WW or EOP; 19%; 13, 24)., Conclusion: A multi-component weight management programme may be beneficial for weight loss, but a randomized controlled trial is needed to establish effectiveness and to evaluate cost.

Objectives: We evaluated the weight loss effectiveness of a YMCA model for the Diabetes Prevention Program (DPP) lifestyle intervention., Methods: Between July 2008 and November 2010, we individually randomized 509 overweight or obese, low-income, nondiabetic adults with elevated blood glucose in Indianapolis, Indiana, to receive standard care plus brief lifestyle counseling or be offered a group-based YMCA adaptation of the DPP (YDPP). Primary outcome was mean weight loss difference at 12 months. In our intention-to-treat analyses, we used longitudinal linear or logistic regression, multiply imputing missing observations. We used instrumental variables regression to estimate weight loss effectiveness among participants completing 9 or more intervention lessons., Results: In the YDPP arm, 161 (62.6%) participants attended ≥ 1 lesson and 103 (40.0%) completed 9 or more lessons. In intention-to-treat analysis, mean 12-month weight loss was 2.3 kilograms (95% confidence interval [CI] = 1.1, 3.4 kg) more for the YDPP arm than for standard care participants. In instrumental variable analyses, persons attending 9 or more lessons had a 5.3-kilogram (95% CI = 2.8, 7.9 kg) greater weight loss than did those with standard care alone., Conclusions: The YMCA model for DPP delivery achieves meaningful weight loss at 12 months among low-income adults.

We conducted a systematic review and meta-analysis investigating the components and effectiveness of self-help weight-loss interventions and their applicability to less-advantaged populations. We searched (November 2013) for randomized controlled trials comparing self-help interventions with each other or with minimal controls in overweight and obese adults, with 6 months or longer follow-up. We calculated mean difference between intervention and control for 6- and 12-month weight change. Twenty-three studies met the inclusion criteria (9632 participants; 39 intervention arms). Intervention participants lost significantly more weight than controls at 6 months (mean difference -1.85 kg; 95% confidence interval [CI]=-2.86, -0.83; 7 studies). No significant effect was detected at 12 months but results were sensitive to the inclusion of 1 study at high risk of bias. Interactive programs appeared more effective than standard ones at 6 months (mean difference -0.94 kg; 95% CI=-1.50, -0.38). Evidence is insufficient to reach conclusions on effectiveness in socioeconomically disadvantaged people, but suggests self-help interventions may be less effective in this group.

Background: Socioeconomic inequalities in obesity are well established in high-income countries. There is a lack of evidence of the types of intervention that are effective in reducing these inequalities among adults., Objectives: To systematically review studies of the effectiveness of individual, community and societal interventions in reducing socio-economic inequalities in obesity among adults., Methods: Nine electronic databases were searched from start date to October 2012 along with website and grey literature searches. The review examined the best available international evidence (both experimental and observational) of interventions at an individual, community and societal level that might reduce inequalities in obesity among adults (aged 18 years or over) in any setting and country. Studies were included if they reported a body fatness-related outcome and if they included a measure of socio-economic status. Data extraction and quality appraisal were conducted using established mechanisms and narrative synthesis was conducted., Results: The 'best available' international evidence was provided by 20 studies. At the individual level, there was evidence of the effectiveness of primary care delivered tailored weight loss programmes among deprived groups. Community based behavioural weight loss interventions and community diet clubs (including workplace ones) also had some evidence of effectiveness-at least in the short term. Societal level evaluations were few, low quality and inconclusive. Further, there was little evidence of long term effectiveness, and few studies of men or outside the USA. However, there was no evidence to suggest that interventions increase inequalities., Conclusions: The best available international evidence suggests that some individual and community-based interventions may be effective in reducing socio-economic inequalities in obesity among adults in the short term. Further research is required particularly of more complex, multi-faceted and societal-level interventions.

Background: While numerous studies highlight the relevance of socio-cultural factors influencing incidence and prevalence of obesity, only a few address how obese people perceive causes and prevention of or intervention for obesity. This study contributes to a more thorough understanding of subjective aetiologies and framing themes for a mainly understudied but promising field. Thus it may serve for the development of effective public health strategies to combat obesity., Methods: Autobiographically based in-depth interviews were conducted with 20 patients (adolescents and young adults) institutionalised in the obesity rehabilitation centre INSULA in Bischofswiesen (Germany). The data were analysed with Atlas.ti with regard to two main perspectives: (1) How the interviewees perceive 'their' obesity from a subjective point of view and (2) which conclusions they draw from their own 'story' concerning prevention/intervention strategies., Results: The interviewees did not indicate a clear starting point for their overweight. Nevertheless, certain life-events (e.g. divorce or illness of parents) were identified as catalysing weight gain. As a consequence of coping with distress, body weight rises rapidly and not continuously. Obesity was generally framed as a problem primarily located within the family and not in the wider environment. Corresponding to this, the family was identified as the main and most important addressee of preventive measures. The interviewees highlighted the importance of personal responsibility as a prerequisite for self-determined action against obesity, but denied any link between responsibility and guilt., Conclusions: This study contributes substantially to a broader perspective on the prevention of obesity. First, more attention has to be paid to the interactions of medical aspects and the social dimension of obesity. Second, prevention efforts should be more aware of the relevance of subjective aetiology when it comes to the definition of reasonable and effective governance strategies in tackling obesity. Third, current assumptions concerning the importance of personal responsibility for obesity prevention might underestimate the relevance of self-determined action of the obese.

The present multi-centre randomised weight-loss trial evaluated the efficacy of a low-intensity 12-week online behavioural modification programme, with or without a fortified diet beverage using a 2 × 2 factorial design. A total of 572 participants were randomised to: (1) an online basic lifestyle information (OBLI) intervention, consisting of one online informational class about tips for weight management; (2) an online behavioural weight management (OBWM) intervention, entailing 12 weekly online classes focused on weight-loss behaviour modification; (3) an OBLI intervention plus a fortified diet cola beverage (BEV) containing green tea extract (total catechin 167 mg), soluble fibre dextrin (10 g) and caffeine (100 mg) (OBLI+BEV); (4) OBWM+BEV. Assessments included height, weight, dual-energy X-ray absorptiometry-derived body composition, and waist circumference (WC). Attrition was 15·7 %. Intention-to-treat (ITT) models demonstrated a main effect for type of Internet programme, with those assigned to the OBWM condition losing significantly more weight (F= 7·174; P= 0·008) and fat mass (F= 4·491; P= 0·035) than those assigned to the OBLI condition. However, there was no significant main effect for the OBWM condition on body fat percentage (F= 2·906; P= 0·089) or WC (F= 3·351; P= 0·068), and no significant main effect for beverage use or significant interactions between factors in ITT models. A 12-week, low-intensity behaviourally based online programme produced a greater weight loss than a basic information website. The addition of a fortified diet beverage had no additional impact.

Background: Despite U.S. Preventive Services Task Force recommendations, few primary care providers (PCPs) counsel obese patients about weight loss. The POWER practice-based weight loss trial used health coaches to provide weight loss counseling, but PCPs referred their patients and reviewed their patients' progress reports. This trial provided a unique opportunity to understand PCPs' actual and desired roles in a multi-component weight loss intervention., Objective: 1) To explore the PCP role, inclusive of and beyond the trial's intended role, in a practice-based weight loss trial; and 2) to elicit recommendations by PCPs for wider dissemination of the successful multi-component program., Design: Qualitative focus group study of PCPs with ≥ 4 patients enrolled in trial., Participants: Twenty-six out of 30 PCPs from six community practices participated between June and August 2010., Main Measures: We used a semi-structured moderator guide. Focus groups were audio-recorded and transcribed verbatim. Two investigators independently coded transcripts for thematic content, identified meaningful segments within the responses and assigned codes using an editing style analysis. Atlas.ti software was used for organization/analysis., Main Results: We identified five major themes related to the PCP's role in patients' weight management: (1) refer patients into program, provide endorsement; (2) provide accountability for patients; (3) "cheerlead" for patients during visits; (4) have limited role in weight management; and (5) maintain the long-term trusting relationship through the ups and downs. PCPs provided several recommendations for wider dissemination of the program into primary care practices, highlighting the need for specific feedback from coaches as well as efficient, integrated processes., Conclusions: Weight loss programs have the potential to partner with PCPs to build upon the patient-provider relationship to improve patient accountability and sustain behavior change. However, rather than directing the weight loss, PCPs preferred a peripheral role by utilizing health coaches.

Weight-loss maintenance is widely accepted to be a difficult and often elusive process. The transtheoretical model (TTM) provides a useful description of five stages of change. Applied to weight management, weight loss occurs during the action stage and weight-loss maintenance occurs during the maintenance stage. Despite its broad utility, the TTM does not adequately explain the complexity involved with a shift from action to maintenance. Based on Engel's (G. L. Engel, 1977, The need for a new medical model: A challenge for biomedicine, Science, Vol. 196, pp. 129-136) biopsychosocial model and family systems theory, a shifting processes model is proposed to describe the potential differences and shift that occurs between weight loss and weight-loss maintenance processes within relational contexts.

Background: Despite record rates of childhood obesity, effective evidence-based treatments remain elusive. While prolonged tertiary specialist clinical input has some individual impact, these services are only available to very few children. Effective treatments that are easily accessible for all overweight and obese children in the community are urgently required. General practitioners are logical care providers for obese children but high-quality trials indicate that, even with substantial training and support, general practitioner care alone will not suffice to improve body mass index (BMI) trajectories. HopSCOTCH (the Shared Care Obesity Trial in Children) will determine whether a shared-care model, in which paediatric obesity specialists co-manage obesity with general practitioners, can improve adiposity in obese children., Design: Randomised controlled trial nested within a cross-sectional BMI survey conducted across 22 general practices in Melbourne, Australia., Participants: Children aged 3-10 years identified as obese by Centers for Disease Control criteria at their family practice, and randomised to either a shared-care intervention or usual care., Intervention: A single multidisciplinary obesity clinic appointment at Melbourne's Royal Children's Hospital, followed by regular appointments with the child's general practitioner over a 12 month period. To support both specialist and general practice consultations, web-based shared-care software was developed to record assessment, set goals and actions, provide information to caregivers, facilitate communication between the two professional groups, and jointly track progress., Outcomes: Primary - change in BMI z-score. Secondary - change in percentage fat and waist circumference; health status, body satisfaction and global self-worth., Discussion: This will be the first efficacy trial of a general-practitioner based, shared-care model of childhood obesity management. If effective, it could greatly improve access to care for obese children., Trial Registration: Australian New Zealand Clinical Trials Registry ACTRN12608000055303.

Background: The 'Healthy Dads, Healthy Kids' program was designed to help overweight fathers lose weight and positively influence the health behaviors of their children. The aim of the current study was to evaluate the previously established program in a community setting, in a large effectiveness trial., Methods/design: The Healthy Dads, Healthy Kids community trial consists of three stages: (i) Stage 1 - program refinement and resource development (ii) Stage 2 - community randomized controlled trial (iii) Stage 3 - community effectiveness trial. The program will be evaluated in five Local Government Areas in the Hunter Valley Region of NSW, Australia. For the community randomized controlled trial, 50 overweight/obese men (aged 18-65 years) from one Local Government Area with a child aged between 5-12 years of age will be recruited. Families will be randomized to either the program or a 6-month wait-list control group. Fathers and their children will be assessed at baseline, post-intervention (3-months) and 6-months. Inclusion criteria are: body mass index 25-40 kg/m2; no participation in other weight loss programs during the study; pass a health-screening questionnaire; and access to a computer with Internet facilities. In the community trial, the program will be evaluated using a non-randomized, prospective design in five Local Government Areas. The exclusion criteria is body mass index < 25 kg/m2 or lack of doctor's approval. MEASURES will be collected at baseline, 3-, 6- and 12-months. The program involves fathers attending seven face-to-face group sessions (three with children) over 3-months., Measures: The primary outcome is fathers' weight. Secondary outcomes for both fathers and children include: waist circumference, blood pressure, resting heart rate, physical activity, sedentary behaviors and dietary intake. Father-only measures include portion size, alcohol consumption, parenting for physical activity and nutrition and parental engagement. Process evaluation will determine the fidelity, dose (delivered and received), reach, recruitment and context of the program., Discussion: As a unique approach to reducing obesity prevalence in men and improving lifestyle behaviours in children, our findings will provide important evidence relating to the translation of Healthy Dads, Healthy Kids, which will enable it to be delivered on a larger scale., Trial Registration: Australia and New Zealand Clinical Trials Register (ANZCTR): ACTRN12610000608066.

Background: The scale of overweight and obesity in the UK places a considerable burden on the NHS. In some areas the NHS has formed partnerships with commercial companies to offer weight management services, but there has been little evaluation of these schemes.This study is an independent audit of the Weight Watchers NHS Referral scheme and evaluates the weight change of obese and overweight adults referred to Weight Watchers (WW) by the NHS., Method: Data was obtained from the WW NHS Referral Scheme database for 29,326 referral courses started after 2nd April 2007 and ending before 6th October 2009 [90% female; median age 49 years (IQR 38-61 years); median BMI 35.1 kg/m2 (IQR 31.8-39.5 kg/m2). Participants received vouchers (funded by the PCT following referral by a healthcare professional) to attend 12 WW meetings. Body weight was measured at WW meetings and relayed to the central database., Results: Median weight change for all referrals was -2.8 kg [IQR -5.9--0.7 kg] representing -3.1% initial weight. 33% of all courses resulted in loss of ≥5% initial weight. 54% of courses were completed. Median weight change for those completing a first course was -5.4 kg [IQR -7.8--3.1 kg] or -5.6% of initial weight. 57% lost ≥5% initial weight., Conclusions: A third of all patients who were referred to WW through the WW NHS Referral Scheme and started a 12 session course achieved ≥5% weight loss, which is usually associated with clinical benefits. This is the largest audit of NHS referral to a commercial weight loss programme in the UK and results are comparable with other options for weight loss available through primary care.
